In science news: I recently used the word "angstrom" in a humorous context, and many people laughed, and some people sneered (mostly engineers), and the wonderful Melissa Evans just gave me the facts, ma'am:

A new imaging technique developed by researchers at the University of Illinois overcomes the limit of diffraction and can reveal the atomic structure of a single nanocrystal with a resolution of less than one angstrom (less than one hundred-millionth of a centimeter).

It was a circular floor, almost a thousand feet in diameter, domed with a double layer of controlled quartz that could give graded illumination from full to total darkness including monochrome light to within one tenth of an angstrom.

Quite a large and nifty machine (the size of a mainframe of the time, which my G-4 beats ten ways to sideways right now even though it's obsolete), and these crystals (rated 1.0 and 0.02 angstrom) were grown specifically for the technology in extremely difficult electromagnetic circumstances, and were at the time more precious than diamonds.

Ha! Though that implies your emotional pain is very, very small, since an angstrom is also "A unit of measure for a wavelength of light equal to ten one billionths of a meter or one-tenth of a nanometer. 10^-10 meters", according to this.
